P2p Applications

P2P networks have caught the imagination of the research community and application developers with their sheer scalability and fault-tolerance characteristics. However, only content-sharing applications based on the P2P concept have reached the desired level of maturity. The potential of the P2P concept for designing the next-generation of real-world distributed applications can be realized only if a comprehensive framework quantifying the performance related aspects of all classes of P2P applications is available. Researchers have proposed some QoS (Quality-of-Service) parameters for content-sharing P2P applications based on response time and delay, but these do not cover the gamut of application domains that the P2P concept is applicable to. Hence, this research paper proposes an early QoS framework covering various classes of P2P applications; content distribution, distributed computing and communication and collaboration. Early results from the prototype implementation of the Peer Enterprises framework (a cross-organizational P2P collaborative application) are used as a basis for formulation of the QoS parameters. The individual performance measures which comprise the QoS framework are also discussed in detail along with some thoughts on how these can be complied with. The proposed framework would hopefully lead to quantifiable Service-Level Agreements for a variety of peer-to-peer services and applications.

This study aims to analyze the influence of tax audit against the compliance level of corporate taxpayer to fulfilling the taxation obligations in KPP Pratama Manado(Manado Small Tax Office). The analysis method used in this research is descriptive to describe the influence of tax audit against the compliance level of corporate taxpayer to fulfilling the taxation obligations in KPP Pratama Manado. Based on the partial research results note that taxation has an influence on the socialization of individual taxpayer compliance, quality of service tax authorities have no effect on an individual taxpayer compliance and tax penalties have no effect on an individual taxpayer compliance. While based on research results simultaneously, socialization taxation, quality of service tax authorities and tax penalties as independent variables jointly affect the individual taxpayer compliance. Suggestions for KPP Pratama Manado is tax officials should be more active in conducting counseling and socialization taxes, behave professionally to serve taxpayers and improve tax penalties for taxpayers who do not comply.

The Impact

This study analyzed the relationship between humans as users of the system and application software as object an inseparable relationship. The purpose of this study was to analyze the effect of variable quality system to the perception of the quality system, the effect of perceived quality system and quality of information on the intensity of use and user satisfaction, and the influence of the intensity of use and user satisfaction of the impact of individual performance. This research is an empirical study using purposive sampling technique in data collection. Data were collected through  questionnaires to 39 BMT’s operational employees. Then, performed an analysis of the data obtained used path analysis. This included: testing hypotheses through path analysis. The results of tests performed using path analysis to get the results that each variable in the model of equation 4 had a coefficient with a positive direction. This means that the improvement of the quality of the system will be able to improve the quality of information for the individual impact of the use and satisfaction of employees through the use of the system.

Auto Scaling

Auto-scaling is one of the most important features in Cloud computing. This feature promises cloud computing customers the ability to best adapt the capacity of their systems to the load they are facing while maintaining the Quality of Service (QoS). This adaptation will be done automatically by increasing or decreasing the amount of resources being leveraged against the workload’s resource demands. There are two types and several techniques of auto-scaling proposed in the literature. However, regardless the type or technique of auto-scaling used, over-provisioning or under-provisioning problem is often observed. In this paper, we model the auto-scaling mechanism with the Stochastic Well-formed coloured Nets (SWN). The simulation of the SWN model allows us to find the state of the system (the number of requests to be dispatched, the idle times of the started resources) from which the auto-scaling mechanism must be operated in order to minimize the amount of used resources without violating the service-level agreements (SLA).

This chapter considers communication issues for small and medium enterprises (SMEs) from both provider and customer perspectives. SME communication infrastructure at the individual site should usually be built around Ethernet-based local area network with a remotely manageable integrated access device that enables high speed Internet access, virtual private networking, Voice over Internet Protocol (VoIP) functionality and collaborative services. We further address several open quality of service (QoS) issues that include: service level agreements, signaling for quality of service and management aspects. The proposed framework for service management encompasses interfaces for QoS-aware and legacy applications, generic service level specification, functional model of service negotiation and management policies.

Monitoring Service

A key requirement in Service Level Management (SLM) is managing the Quality of Services (QoS) demanded by clients and offered by providers. This managing process is complicated by the globalization and Internet scale of enterprise services and their compositions. This chapter presents two contributions to the QoS management task for SLM. First, instead of considering monitoring as an isolated service, it incorporates a monitoring service as an integral part of a comprehensive QoS management framework for SLM. Second, it includes a diagnosis service as an integral part of the QoS management framework. Using the data fed from monitoring service, diagnosis service detects system condition changes and reasons about the causes of detected degradation in networked enterprise system. With condition detection and situation understanding, the QoS management framework can then proactively activate adaptation mechanisms to maximize the system’s ability to meet QoS contract requirements of concurrent clients. Using this framework, enterprise systems can provide real time automated QoS management to optimize system resources in meeting contract requirements. This approach is validated using QoS management services integrated in a publish/subscribe style of SOA. Benefits of QoS monitoring, diagnosis, and adaptation services for responsiveness SLM are demonstrated via experiments.
